PLEASE NOTE: Since plants are often sourced from the garden to order, sizes do vary a little, depending on how they come out of the ground, but I always endeavour to give a little more rather than less! They are sometimes shipped bare-rooted, but will approximate the size specified (e.g. a 9cm pot).
|Alcea rosea Ex. 'Jet Black'|
|Hollyhock, Ex. 'Jet Black'|
|Deepest, deepest red-purple - as close to black as you can get! Although strictly speaking a perennial, this very popular cottage garden plant is best treated as a biennial, particularly since it can be susceptible to rust. These are very tall plants and some support is recommended.
NOTE: Since other hollyhocks are grown in the garden there is the possibility of some cross-breeding. This applies both to seeds and to plants, when offered.
|Sowing and/or growing instructions|
|Can be direct sown in late summer or spring. Alternatively sow on the surface, barely covering with compost, under glass in mid-winter, either singly in modules or small pots, or in seed trays for transplanting when the first true leaves have developed. Although best treated as biennials, hollyhocks will often survive for a number of years. However, they are prone to rust so it is best to replace plants regularly. Cut back after first flowers are almost spent to encourage new, albeit shorter, flower spikes.|
