Dioon edule (Chestnut Edule) seeds
Versatile and highly ornamental Mexican cycad with stiff, blue green, fern like leaves which are very attractive even on small seedlings. A robust plant, it does well in any well drained soil, copes well with drought and coastal winds and tolerates frosts down to -10C. Can be grown outdoors, indoors and even makes a great bonsai. Very easy to grow.
Hardy Palm (Hardy to -10C when mature)
Height: 1.2 - 1.8m, smaller indoors
Position: Full sun or semi shade in well drained soil
Packet of 5 seeds
Sow at any time of year.
Pre-sowing Treatment: Soak the seeds until the seed coat splits (this can take several weeks or even months) changing the water every few days preferably in a heated propagator, or on a sunny windowsill or above a radiator.
Sowing Instructions: When the seed coat splits, place in small pots of moist seed compost mixed 50:50 with vermiculite. The seeds should be half buried lengthwise with the split just visible at soil level. Place in a propagator or cover with a polythene bag and place in any other warm place (eg. on a windowsill above a radiator). Palm seeds often make a large root before a shoot so carefully check seeds regularly. When a root appears, pot up individually into 9-11cm pots. Germination can be erratic but should take place in 1 – 3 months.
Growing Instructions: Grow the seedlings on, re-potting as necessary and protect from frost for the first couple of winters. Harden off completely before planting out in a sunny, sheltered position away from strong winds which can tear the leaves. Protect with bubble wrap and/or a fleece jacket for the first few years and in very cold temperatures.
