Black Velvet Nasturtium Seeds Reviews

Hardy plant

This was the first time I’ve ever started flowers from seed. I soaked the seeds per instructions and started these indoors in medium biodegradable containers. All of them germinated and thrived. These were extremely hardy flowers. They each grew to take up about 1.5′ to 2′ of space with lots and lots of blooms. I have so many blooms that I frequently pluck and dry them to mix in with my chicken treats. They didn’t attract a ton of pollinators like some of my other plants but I did see them flying around. The flowers are a tad shorter than the leaves so in the early stages of growth there is more green than red. They were fun to grow!

Black Velvet Nasturtium Seeds

Black Velvet Nasturtiums

Owner Response: Hi Catherine, Thanks for sharing your experience. We have a tip that may be helpful for nasturtium blooms. Nasturtiums are quite sensitive to nitrogen and will produce big, lovely foliage and not flower if there is too much. For instance, potting soil can have a lot of nitrogen in it that takes a few months to leach out through watering. We hope this helps!

Foliage or Blooms – No Inbetween

I’ve been growing nasturtiums for years. The color of the Black Velvet really caught my attention so it was game on. They took a little longer than two weeks to germinate. Good germination rate, maybe 85%. Huge amount of foliage and it took weeks for the first buds to appear. When the flowers came, they came on in a rush. A lot of them, all at one time. And when the flowers came, all the foliage died off, leaving a plant that looked hideous. It looked so bad in fact that I pulled the plants two weeks after they started blooming. Beautiful big burgundy color blooms – hideous plant overall. I don’t recommend this variety.

Owner Response: Hello, This is abnormal behavior for this plant. Nasturtiums are especially sensitive to rich growing conditions. Stress can also cause plants to flower profusely as they try to form seed to reproduce as a reaction. We are sorry you had a bad experience with this cultivar.


Gorgeous dark red flowers and purple tinged vines. They didn’t like the hot, dry, conditions in our yard. Would grow again in a cooler, wetter location.

Beautiful flower – all red, no black.

I grew several of these throughout my yard and have really enjoyed them. I was however hoping to get black (or near to black) flowers, but all of them were a rich red color.

Owner Response: Hi Sergio, You are right, these are a deep ruby color. While a lot of flowers are described as black it is almost unheard of in nature. We hope the illustration and description gave a good depiction of what to expect. Happy gardening!

well packaged

I won’t be planting anything I ordered until next year, but the packaging is instructive, and your selection is good. I hope to have good results next season.

late summer/early fall blooms in zone 6

this was my first time growing this particular species of nasturtium, and in zone 6, they seemed much happier as summer came to an end. it wasn’t particularly hot this year, nor dry, but my plants got new growth and far more blooms later in the season, which is different from what i experienced in the past with other nasturtium species. the color of the blooms matched the illustration, and when pressed and dried, they were black. would recommend, especially for those planning fall gardens.

easy to grow

just great!

I added this variety to last years nasturtium area in my garden and they really produced the most beautiful and prolific flowers. I am hoping to see them come back this summer too.


Tropaeolum majus The deepest, darkest, richest, ruby-black blooms grace tidy plants. For a dramatically thrilling display, Black Velvet provides maximum contrast to light-colored flowers or a provocative mix with purples and reds. Mounding plants reach 12 inches tall. By providing adequate water and clipping seed heads, your nasturtiums will reward you with a profusion of blooms from July to fall’s first frost. The flowers make a lightly spicy edible garnish too! Approximately 7 seeds per gram. Germination code: (4)

Germination Codes
Given at the end of each description to give you specific information.
(1) Germination occurs between 70-85°F and within 6-15 days. Sow indoors and cover lightly.
(2) Needs a period of pre-chilling. Mix seeds with moistened peat moss and place in plastic bag. Seal and place bag in an area where the temperature is around 60°F for 2-3 days. Then place in the refrigerator for 30-90 days. After pre-chilling, place seed on sterile seedling mix and cover lightly. Germination may take up to 30 days.
(3) Needs darkness to germinate. Remove cover as soon as germination occurs.
(4) Direct sow in the garden as soon as the soil warms to at least 55°F.
(5) Germination may be slow and erratic. A fluctuating temperature of 75°F during the day and 50°F at night may help.
(6) Needs at least 12 hours of light per day to germinate. Press into the medium but do not cover. Keep moist.
Note: For those varieties that indicate a (1) or (6), a very light covering of vermiculite will allow adequate light to the seed and keep it uniformly moist.

• As a general rule, flowers can be sown when soil has warmed to at least 55°F
• Apply 1-2 cups of TSC’s Complete fertilizer per 5 row feet, and 1 inch of compost
• If you prefer to soak your seeds: soak in 85°F water for 1-3 hours and plant immediately — longer soaking times are often detrimental; seeds need air to live

Direct Sowing
• Seeds should be buried 2 times their narrowest dimension and covered with finely raked soil or vermiculite unless otherwise noted
• Some varieties can take over a month to germinate so mark your rows, keep them moist, and for larger seeds like sunflowers, use bird netting

• Sow 5-6 weeks prior to anticipated transplant date
• If seeds need darkness, cover with 2 sheets of newspaper or plastic, remove upon the first signs of germination
• We recommend feeding your seedlings Age Old Grow, diluted to 1/4 strength

Insects & Disease
• Early watering and good weed control will generally alleviate most problems
• Pyrethrin will control most insects

Harvest & Storage
• For fresh-cut flowers: Harvest in the morning when flowers are their freshest and petals are just opening
• Cut with a clean knife that has been dipped in a solution of 10% household bleach
• A few drops of bleach in the vase will prolong their beauty
