Trichostema Blue Bonnets
In stock
Description
This extremely rare new plant has strong stems which extend to 5 or 6 feet through the summer and astonishingly only bud up in September! Clouds of bright cobalt-blue flowers, resembling tiny orchids with huge reflexed stamens, then open, in September and October, amidst musty-smelling leaves. This truly amazing, non-invasive, completely hardy new plant adds colour to our garden when almost all other flowers have long-gone!
Sowing Advice
Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
