24+ Deep Blue Butterfly Pea Vine Seeds, Clitoria, Lovely! You are buying 24+ Blue Butterfly Pea (Clitoria ternatea) Seeds PLUS planting instructions. These are fresh seeds which I have germination tested with very good results. These are tender/tropical perennials in zones 9b (sometimes 9a if protected) and warmer, grow as annuals or even house plants in colder zones. Will self-sow for even more vines in following years! Dont be surprised if the Long Tailed Skipper or Painted Lady butterfly show up because this plant is one of their larval (host) foods. This vine grows to about 15' and will be covered with blooms from mid-summer into fall. It readily self-seeds itself for even more plants in coming years. An excellent addition for your BUTTERFLY garden. They grow best in sandy, well draining, average soil and in bright/partial shade. Drought tolerant once established. Our seeds/bulbs are guaranteed to be fresh but are NOT guaranteed as to results. Sorry, but there are too many variables in gardening that can impact germination. Flower seeds/bulbs are a live organism. Their germination depends on many factor including heat, cooling, sun, shade, moisture, time of sowing, etc. None of these things We can control so We can not be held responsible for them. So please do not ask for a refund, replacement or to return unused seeds/bulbs.
