PRODUCT DESCRIPTION
Hollyhock Chater's Double Mix Alcea Rosea is a hardy biennial flowering plant. Hollyhock Chater's Double Mix seeds can be started directly outdoors or indoors and in pots in a cold frame. Hollyhock Chater's Double Mix variety produces fully-double scarlet, pink, white, purple, eggplant and yellow flowers that are 7-12cm across and densely clustered together on the sturdy flower spikes. Hollyhock flowers grow on rigid, towering spikes or spires which typically reach a height of 1.5-2m tall, and the foliage features large, heart-shaped, rough lower leaves which become progressively smaller toward the top of the spire. Alcea Rosea are base branching and bloom from May to October attracting hummingbirds and butterflies.
Hollyhock Chater's Double Mix is an old time favourite for cottage, wildflower, wildlife gardens, and flower beds. Hollyhock's fully-double flowers are perfect for the back of borders and along fences and walls. Alcea Rosea seeds can be planted in August or September for bloom the following year, and the established Hollyhock grows in average, medium moisture, well-drained soil in full sun, tolerating a wide range of soil conditions and some light shade. If grown from seed, the although short-lived, Hollyhocks easily self-seed, and they can establish colonies that persist for years as if they were perennials.

How to grow Hollyhock Chater's Double seeds
Transplant seedlings when large enough to handle into trays or 7.5cm pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 45cm apart.
Rust remedies
Hollyhocks are archetypal cottage garden plants (you often see them growing beautifully in churchyards). The cleaner, sulphur-free air that we all now enjoy, however, means that fungus on roses and hollyhocks is more common. Both plants need tinkering to be at their best.
Rust fungus forms little pustules on the underside of hollyhock basal leaves and often spreads from there up the stem. If you want to grow your hollyhocks right by a path, they need to look vigorous and healthy. The only way to guarantee this is to use fungicides. If Bordeaux mixture, a traditional copper sulphate-derived remedy, is not enough to hold rust at bay, you may need to use stronger fungicides.
If this all feels far too much like chemical warfare, ignore any rust problems and hide the foliage of your hollyhocks by putting them nearer the back of the border.
Make more plants
Hollyhocks self-sow, so once you have introduced them they should spring up of their own volition, but they will creep to the sunny, open front of the bed. Watch out for this and dig some up and put them further back out of the limelight to get a balanced sweep. Don't transfer them directly, though – they need a short spell of TLC.
Dig up self-sown seedlings and pot them into a 7cm pot. Once the roots have filled it, move them on into a slim, deep pot to accommodate the tap root.
