Geum Rivale 'Lemon Drops'
From a compact clump of wrinkled leaves arise short hairy stems holding the palest greeny-lemon nodding bells, which open from late spring to early summer and yet again in autumn. Although it performs best in moist soils, it will grow happily in the driest, sunniest spot in your garden. The original "Lemon Drops" was a chance hybrid seedling, with presumably some of the blood of Geum avens, from Beth Chatto's wonderful Essex garden, and these seedlings may have the slightest bit of variation but all will be lovely.
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.
