Even here, climate is not perfect. It may sometimes seem to be too warm during summer. However, it might not be consistently warm and humid enough for some tropical species. Winter chill may be inadequate to vernalize some species or certain cultivars of species. However, recently frosty weather has already damaged some vegetation in some areas.

Frost limits what performs well in home gardens in two extremes. Some species prefer a bit more than they experience here. Others prefer less. For example, peony prefers more, while vanilla orchid prefers none. Peony is only marginal where weather is exceptionally frosty by local standards. Vanilla orchid can be offended by minor chill even without frost.

Climates and microclimates limit frost just as frost limits what performs in home gardens. Some coastal climates here only very rarely or perhaps never experience frosty weather. Other climates farther inland or at higher elevations experience frost almost every winter. Within such climates, eaves or canopies of big trees can provide shelter from minor frost.

Vegetation within home gardens should be appropriate to its particular climate. Varieties that are vulnerable to frosty weather are likely safe where frost never occurs. Conversely, they will obviously be susceptible to damage where frost does occur. The best means to avoid such damage is appropriate selection. Climate will not accommodate bad choices.

Gardening could be slightly less interesting without a few bad choices, though. Besides, some of such choices are justifiable with the right perspective. Canna, for example, dies back harmlessly to dormant rhizomes after frosty weather. It wastes no time regenerating as weather warms. Some tropical species may grow in pots to move to shelter from frost.

Tenting can shelter some specimens that are too big to move, or are in the ground. Outer foliage that already succumbed to frosty weather can shelter inner growth. Therefore, if it is not too unsightly, it should remain through winter. Besides, premature pruning is likely to stimulate new growth. Such growth would innately be vulnerable to subsequent frosts.
