Their web site says, "This customer favourite variety is back!" so not completely new to Mr Fothergills for 2023, but to me up until now courgettes are and have been mini green long mini marrow like plants, that if you don't pick them at the right time turn into marrows!
Summer Holliday produce large crops of rounded, colourful and eye-catching beach ball looking courgettes. Again, Mr Fothergills web page says they are "Very popular in Italy, their shape makes them ideal for stuffing, or steamed whole."
Packed with great flavour and texture, they are an excellent source of vitamin C.
for surest results, 13mm(½in) deep, on edge, in small pots of compost. Water well and place in a warm position. A temperature of 15-20°C(60-68°F) is ideal. Keep moist. Seedlings usually appear in 7-14 days. Gradually accustom plants to outside conditions (avoid frosts), before planting out 600mm(2ft) apart, when frosts are over.
for ease, where they are to crop, 13cm(½in) deep directly into finely prepared soil which has already been watered. Allow 600mm (2ft) between sowing positions. Sow two seeds on edge per position. Early sowings benefit from cloche protection. Thin to leave the stronger plant. Water well until plants are established.
