Like with most vegetables, taste is most dependent upon cultivar. Age and rapidity of growth does have some effect. The store bought "baby " carrots are Imperator types carved down. These are the long blunt carrots, but they don't do well in clay soils. As long as the carrots get adequate growth before freezes, they will hold through the winter. They will try to seed in spring however, so unless you are saving seed, use them in the winter.

I'd vote for maybe Meyer lemon? they are more round than other lemons, color up a little more orange color that most lemons but are definitely lemon flavor, just a little less acid that most lemons but still tart, and the dark bark for an in ground tree is about right. the exact parentage of Meyer is not known, as it was discovered in the open, rather than part of a breeding program, but some have speculated that it may have been a cross with a lemon and an orange.

Some varieties fall when they are over mature; others hang. Don't judge your fruit by the fruit that was forced there to sell the tree; too much Nitrogen for sure, together with over ripe by December in Florida. Transplant the tree to the ground or to a larger pot; treat it to a good balanced citrus food and some essential minerals either by soil or foliar application; and you will likely find the fruits more numerous, maybe a bit smaller, and more tasty the next crop. You should pick off all the fruits now, if you haven't already; if you leave them now you will reduce next year crop and stifle the growth of the tree.

I live in northern Poland and I am a fond of raspberries as well. My favourites are : Canby - thornless, summer Pokusa - autumn and Rubus illecebrosus - used as a vegetable. We can exchange plants if you wish. Milin
