Learn Spanish (Latin America): Mi jardín ideal es muy soleado.

Usually, to say "it is sunny right now," you would use está soleado (a temporary condition) or hace sol. However, in this sentence, you are describing a permanent, defining characteristic of your ideal garden, so you must use the verb ser (es).

Why does ideal come after jardín instead of before it?

In Spanish, descriptive adjectives like ideal usually come directly after the noun they modify to distinguish it from other things (in this case, other types of gardens). Placing it before the noun would sound overly poetic, whereas putting it after makes it a standard description.

This lesson is about the subjunctive. Why isn't there a subjunctive verb in this sentence?

We use the subjunctive when looking for something that might not exist, like "I want a garden that is sunny" (Quiero un jardín que sea soleado). But this specific sentence doesn't have a relative clause (a "that..." phrase). It is just a direct statement defining what your ideal garden is, so it simply uses the regular indicative mood (es).
